Elliott Clark created HADOOP-12450: -------------------------------------- Summary: UserGroupInformation should not log at WARN level if no groups are found Key: HADOOP-12450 URL: https://issues.apache.org/jira/browse/HADOOP-12450 Project: Hadoop Common Issue Type: Bug Reporter: Elliott Clark Assignee: Elliott Clark
HBase tries to get the groups of a user on every request. That user may or may not exist on the box running Hadoop/HBase. If that user doesn't exist currently Hadoop will log at the WARN level everytime. This leads to gigs of log spam and serious GC issues. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
